A synergistic mindsets intervention protects adolescents from stress

Area of Science:

• Psychology
• Adolescent Health
• Educational Psychology

Background:

• Social-evaluative stressors negatively impact adolescent mental health and skill development.
• Adolescents often disengage from challenging activities due to fear of negative judgment.
• Existing interventions may not adequately address the multifaceted nature of adolescent stress.

Purpose of the Study:

• To evaluate the effectiveness of a novel 'synergistic mindsets' intervention for improving adolescent stress responses.
• To determine if combining growth mindsets and stress-can-be-enhancing mindsets yields benefits.
• To assess the intervention's impact on psychological well-being, academic success, and anxiety.

Main Methods:

• Six double-blind, randomized, controlled experiments with secondary and post-secondary students.
• A self-administered, approximately 30-minute online training module.
• Bayesian machine-learning statistical methods to analyze heterogeneous effects.

Main Results:

• The synergistic mindsets intervention improved stress-related cognitions and cardiovascular reactivity.
• Significant reductions in daily cortisol levels and anxiety symptoms were observed.
• Enhanced psychological well-being and academic success were linked to the intervention.

Conclusions:

• A short, scalable 'synergistic mindsets' intervention effectively improves adolescent stress responses.
• The benefits are contingent on synergistically addressing both growth and stress-enhancing mindsets.
• This low-cost intervention shows potential for national-scale implementation to support adolescent mental health.
